I mean blue. I have my D7100 set to auto white balance. I notice that pix taken under deep but bright forest cover are quite blue. Also scenes of flowers along treed roadways are bluish. In all cases the sky above the tree canopy or through the treeline along the road is sunny. I can fix problem in pp (Capture NX2) by changing setting to daylight, shade. Is the camera working okay? Any change of settings recommended? Thanks all. Stephen

A sample image would confirm my thoughts, but your camera is most likely working as it should.
The issue is most likely that AWB (auto-white balance) is designed to work with color temperatures between 3500 and 8000K. Deep shade you are describing can easily reach 9000 to 10000K causing the blue'ish look you're discribing.
If that's the case, then selecting color temperature yourself, or doing a custom white balance would be a better option. Or shooting NEF's and adjusting later in PP as your doing works too.

You've probably, at least partially, answered your own question. If changing white balance to daylight/shade in NX2 fixes the blue colour cast, that's your answer. So whenever you're shooting in the kind of lighting that causes the blue colour cast, set your camera's white balance then the same as you'd set it NX2 to correct the problem.
The other solution is to do a preset manual custom white balance setting whenver you're going to be in difficult lighting (or at least lighting that's difficult for the camera's auto white balance system). Setting a custom white balance using either an 18% grey card or cloth, or even a white t-shirt, takes less than 30 seconds. The results are usually excellent.
Anyway, the simple instructions for doing an on-the-spot preset manual custom white balance is on page 95 of the D7100 manual.
The third method of attacking unwanted colour casts is to set white balance bracketing in the camera configuration settings. Page 137 of the D7100 manual.
Thanks for help. I am surprised that the camera was unable to do the adjustment as it didn't seem that the conditions were extreme. I am having trouble attaching the image. I converted it from Raw to JPEG as a "good" image but still find an error message that indicates it is too large. Any guidance with this!? S
Ok, that appears to be a mixed lighting situation in which there is no one WB setting.
It appears you have streaks of direct sunlight mixed with dense shade. Adjusting for one in camera will throw off the other. Being you are complaining of blue'ish tint, it appears the camera chose the sunlight over the dense shade.
How you handle it depends on the look you want. Choosing an in camera WB for the shade will render that area neutral in hue, but would make the sunlight rays warmer in tone. Correcting for the sunlight rays will make the dense shade areas appear blue'ish.
If you want to correct for both, then selective correction in an PP editor is the only way I would know of.
